Clean install ios7?

Yeah, just restore it in iTunes. Back up your things first, but know that restoring from a back up will defeat the purpose of a clean install.

 

Did you restore from a backup?

 

After you restore in itunes and restore your backup, go to settings>general>reset> and select the "Reset all settings". Then once the device reboots go back through and set it up like you want it. That will not delete apps and such but will default the settings ,network connections and wallpaper. You will need to add back wifi networks.

If that doesn't help then restore again (iTunes) and this time set up as new. Just download all your apps again manually and don't restore a backup and see if it works better.

 

Erase on the phone just wipes your phone clean. Restoring through iTunes completely reinstalls iOS. I'd recommend restoring through iTunes.

 

Update the phone..

 

DFU restore

 

I know. A clean install of iOS 7.1 beta 2 gives me 11:37 usage and 11:50 of standby. So. I'm enjoyingy clean install where on my 5s on 7.0.4 I wasn't getting a full day of battery

 

Same here

 

Turn the iPad mini off.

Open iTunes

Plug in the usb side of the lightning cable into your computer

Hold down the home button of your iPad

Plug in the lighting cable, still holding down the home button

The iPad will boot and display a USB to iTunes image.

iTunes will detect the iPad, and inform you its in restore mode.

On iTunes click restore, and iTunes will do a full clean install of the latest version of i0s 7 available.

 

You said there's a 1 on the Settings icon though.

 

for me helped this, to get rid of really strange bug which some people have:
Reset atleast 2 times settings
Reset all content and settings
Restore from backup

p.s restoring as new or DFU restore didnt help for me

 

No problem

 

If you didn't do it via iTunes you didn't do a restore/reinstall. You just wiped your user data. Nothing in so was touched as it needs iTunes for that.

And yes it reinstalls iOS. It has to or your iPad can't be used.
